From ea29a02fd802d8df8202819f0a50d4ebb960bb2a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 16 Aug 2023 18:02:48 +0200 Subject: ALSA: rawmidi: Don't embed device This patch detaches the struct device from the snd_rawmidi object by allocating via snd_device_alloc(), just like done for other devices.
